Description

TECHNICAL FIELD

[0002] Opening-up machine is special mechanical equipment for agriculture or forestry, for cleaning wasteland, shrubs, small trees etc. Traditional opening-up machine is mainly powered by fuel oil, which needs to be directly driven and operated by manual, and the operation speed is relatively slow, and it is difficult to move quickly in complex terrain and dense shrubs, with low efficiency. Moreover, the operator needs to drive and control the equipment for a long time, with high labor intensity, easy to be tired, affecting work efficiency and safety. In addition, under the opening-up working condition, the height of high grass and shrubs is mostly beyond the height of the equipment, and the traditional equipment is difficult to effectively deal with complex environment, so there is an urgent market demand for remote control or automatic opening-up machine.

[0003] Full-automatic similar equipment is exploring the fusion of AI visual recognition, multi-sensor fusion laser radar + camera to realize centimeter-level obstacle avoidance, combined with satellite remote sensing and unmanned aerial vehicle surveying and mapping to realize accurate terrain analysis and automatic planning of operation path. However, under the opening-up working condition, since the height of high grass and shrubs is mostly beyond the height of the equipment, the advance planning and on-site identification are easily invalidated due to the influence and interference of complex environment in the wild, which makes it difficult to realize the above technical solutions and lacks practicality.

[0004] In the prior art, some technical solutions have tried to solve the above problems. For example, the utility model patent with patent number CN202222419354.2 discloses an agricultural opening-up weeding machine, which adjusts the horizontal height of the weeding part to adapt to shrubs and grasses of different heights.
